THE COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 947 



the ventrum, legs and prologs all a light, very pale, watery green. L : 15 

 mm. ; B : 7-5 mm. including the teeth and about 5 mm. excluding 

 them. 



The colouring is difficult to describe as it is so patchy. There is a touch 

 of yellow behind each spiracle ; the spiracles are situated upon the 

 posterior slopes of the ridges; the tlat-dorsal surface of segments 12-14 

 is somewhat corrugated. 



Pupa. — This is more or less normal in shape but very stout in build. It is 

 highest at segment 7 and there also broadest ; the front end is compara- 

 tively narrowly rounded, the anal end very broadly as segments 10-14 

 have their dorsal line more or less in a lalane perpendicular to the longitu- 

 dinal axis of the pupa ; segment 9' has it inclined at about an angle of 

 45° ; the dorsal line of thorax slopes towards head from the hinder margin 

 in a more or less even, slightly convex line ; the head is nearly altogether 

 ventral, the front margin of segment 2 forming the front of the pupa ,• the 

 shoulders are rounded and hardly promment ; there is a slight wide 

 constriction from them to segment 7 laterally ; dorsally also, segments 4, 5 

 are at a lower level than either the thorax or segment 6. Segment ti is 

 hood-shaped, more or less in the shape of a quarter-sphere but slightly 

 liattened in the dorsal region along the front margin (which is practically 

 in the same plane as the straight ventral line) and very slightly compressed 

 laterally, the dorsal line at an angle of 73° to the longitudinal axis, 

 the hinder margin very nealy straight between the spiracles ; the 

 thorax is twice the length of segment 2 (perhaps a -little more) and, 

 like it, transversely convex, rising from the front margin in the same plane 

 as it also but soon curving round to become nearly parallel to the ventral 

 line or longitudinal axis (which is, here, the same thing ), at the extreme 

 hinder margin it falls gently, the hinder margin is produced backwards in 

 a right angle into segment 4, and each end of this hinder margin meets the 

 wing-line in a widely open, broadly rounded angle of slightly under 90° ; 

 segment 4 is very short in the dorsal line, somewhat extensive laterally ; 

 segment 5 is shorter than the dorsal line of segment 4 ; segments 6-9 inclvi- 

 sive are more than three times as long as 5 and coequal ; segment 10 the 

 same as these ; segments 11 , 12 half as long as them ; segments 13, 14 to- 

 gether (segment 13 practically non-existent) as long as 12. Surface 

 of the pupa is rugose with fine, raised, thin reticulations which are more 

 or less in the form of rays from small, raised points and this is the case all 

 over except in the broad spiracular depressions where there are merely tiny 

 tubercular risings without reticulations ; the hinder margin of segment 9 and 

 the front margin of segment 10 is conspicuously thickened and raised, the 

 former more than the latter — with a narrow depressed interval between ; 

 segments 10, 11 similar but less so ; the whole surface set with short, erect, 

 light brown, pointed, minutely feathered hairs which are longest and den- 

 sest on segment 2 along the front margin and on the three last anal 

 segments, (12-14 ); these hairs as long as the spiracles : the longer ones as 

 long nearly as the spiracles of segment 2. Spiracles of segment 2 are near- 

 ly as long as segment 5 and less than half that breadth, oval, facing forwards 

 and very light pink-brown in colour; the rest are very small, oval, slightly 

 raised, shining and the same colour, each one in a broad, shallow depression 

 of the surface ; that of segment 11 blind, of segment 12 still blinder. The 

 colour is moderately dark brownish pink suffused dorsally and laterally on 

 the abdomen irregularly with brown, on the thorax laterally ; the wings 

 yellowish suffused thickly with brown or olive-brown. L : IT 5mm. : B: 6mm. 

 at segment 7, 4mm. just before shoulders ; the heights at those places the 

 same.
